5. Using On-Screen Menu
NOTE:
When you are displaying an RGB image with a higher resolution than the projector's native resolution, the image will be dis-
played in [Normal] even if [Native] is selected. Only when displaying an RGB image with a lower resolution than the projec-
tor's native resolution, will the image be able to be displayed in its true resolution [Native].
When [Normal] is selected, an HDTV (1080i/720p) signal will be shown in its true aspect, as is the case when selecting [Cinema].
You can adjust the image position for Cinema aspect. See [Cinema Position] for setting the image position.
Copyright
Please note that using this projector for the purpose of commercial gain or the attraction of public attention in a venue such as
a coffee shop or hotel and employing compression or expansion of the screen image with a [Aspect Ratio] setting may raise
concern about the infringement of copyrights which are protected by copyright law.
Adjusting the Vertical Position of Image [Cinema Position] (for Cinema only)
This feature adjusts the vertical position of the image when viewing video with Cinema aspect ratio selected.
When [Cinema] is selected in [Aspect Ratio], the image is displayed with black borders on the top and bottom.
You can adjust the vertical position from the top to the bottom of the black area.
NOTE: This option is available only when “Cinema” is selected in Aspect Ratio.
Adjusting Horizontal/Vertical Position, Clock and Phase [Position/Clock]
You can adjust the image manually for position and stability; [Horizontal], [Vertical], [Clock] and [Phase].
[Horizontal/Vertical] (available for RGB signal only)
Adjusts the image location horizontally and vertically.
[Clock] (available for RGB signal only)
Use this item to fi ne tune the computer image or to remove any vertical banding that might appear. This func-
tion adjusts the clock frequencies that eliminate the horizontal banding in the image. This adjustment may be
necessary when you connect your computer for the fi rst time.
[Phase] (available for RGB signal only)
Use this item to adjust the clock phase or to reduce video noise, dot interference or cross talk. (This is evident
when part of your image appears to be shimmering.)
Use [Phase] only after the [Clock] is complete.
• Performing the [Horizontal], [Vertical], [Clock] or [Phase] function will store the adjustment values of the cur-
rently projected source into the projector’s memory.
The next time the same source (same resolution, horizontal and vertical frequencies) is projected; the projec-
tor will call up from memory the stored values for the source.
To clear the stored adjustment values, select the [Reset] → [Current Signal] or [All Data] from the menu to re-
set the adjustment values.
Turning on Noise Reduction [Noise Reduction]
Turn on or off the noise reduction feature. To reduce video noise, select On.
NOTE:
This feature is not available for 480p, 576p, 720p, 1080i and RGB signals
Noise reduction set to off gives best image quality by way of higher bandwidth. Noise reduction set to on softens the image.
Setting Telecine Mode [Telecine]
Use 3:2 or 2:2 pull down correction to eliminate jitter and artifacts in video.
Auto ....................... For fi lm source such as a DVD player.
Off ......................... For signals other than fi lm sources.
NOTE: This feature is not available for 480p, 576p, 720p, 1080i and RGB signals
